摘要
暴雨洪峰模数法是水文分析计算中进行设计洪水计算较为常用的一种方法,由于其原理简洁,使用直观、方便,其精度也得到验证,因而在设计洪水计算中广为使用,本文根据新疆天山北坡中段各河流暴雨洪水资料,采用相关分析等方法推求洪峰模数与流域平均高程、河道纵坡降之间的关系,分析暴雨洪水洪峰模数在天山北坡中段地区上的分布规律,解决该区域小河(沟)在缺乏实测资料情况下设计暴雨洪水计算方法多样性[1]的途径。
The storm peak modulus method is more commonly used as a method to calculate the design flood hydrology analysis calculations performed ,because the principle is simple ,intuitive, easy to use ,its accuracy has been verified,and thus is widely used in the design flood calculation,this article according to each river storm flood data in the middle of Mountain Tianshan ,using correlation analysis method Derived peak flood modulus and basin average elevation,the relation with river longitudinal slope;It analyzed the storm flood peak modulus distribution law in the middle region of Tianshan Mountain to resolve the region Creek （ditch）design storm flood calculation methods in the absence of measured data.
